PURPOSE: To maintain the function of impact resistance without damage by covering or enclosing a ceramic part of a composite molding of ceramics and a high-strength fiber-reinforced plastic or the entire molding with an impact alleviating cushioning material. CONSTITUTION: A prepreg containing about 20% of a resin is obtained by impregnating a plain weave fabric (METSUKE of 230g/m<2> ) made of a high-strength glass fiber having a specific tensile strength of 16×10<6> cm and a specific modulus of 3.2×10<8> cm with a resol type phenol resin and drying the fabric. The five prepregs are superposed, heated at 150 deg.C and pressurized at 100kg/cm<2> to obtain an ACM plate 1. The ACMITA is fixed to alumina ceramics (thickness of 4mm) 2 having purity of 92% by sticking material 3 made of a phenol resin fased hand lay-up resin to obtain a composite molding A. A synthetic rubber (neoprene) sheet 4 (having a thickness of 2mm) is sticked on the ceramics 1 of the molding A by a synthetic sticking material 5 to obtain a composite molding B.
